Errors When Opening imported Files

Diomedeidae · 08-08-2020, 09:36 AM

Afternoon.

I have this odd error. If I import a book that ends up being a duplicate, corrupts it. If I say do not add duplicates, it put in empty books. IE no formats are entered.

If you select the the first file on the options list it will not corrupt this, but if you are consolidating two databases or the likes of, doing this on 100's of books is just not going to happen.

This is a copy of the error. It is not a zip file.

Failed to convert book: X:\Calibre\Karen Abbott\American Rose (37176)\American Rose - Karen Abbott.epub with error:

According to that error the file you are trying to view is corrupted, or not actually an epub file. When adding files calibre simply copies them byte for byte making NO changes to the files. The only exception being if you have installed thrid party plugins like the DRM removal plugin.

(the path is on) X: ??
Is this a network(ed) drive?

It is on a networked drive. It is on my NAS.
They worked before i started copying them, which is odd. As I mentioned in my initial post, if I click on a specific file to import it works. Very odd.
